Hi guys Iam pretty sure you guys can help me on this
I am pondering the idea of building my first modded saw. The saw of choice I have picked is a 372/371.
The general conception from porting I have got from reading threads is that.
Widen the exhaust/muffler port leaving 1.5mm each side of the skirts.
Do the same on the intake side (or nothing ? )
Clean up transfers but dont lower them ?
Window the piston
Also for a pop up when machining the Piston how do i determine the squish band do like the outside diameter of the piston that needs machined off.
The pop up in a 372 would be .25 thou off top piston leave at least .100 above top ring machine equal amount off cylinder .
If you guys could help that would be great
I dont know if any ideas are hush hush because of the GTG worksaw build off but any basic ideas would be appreciated.
Also a guy on US ebay is selling a 346 ported pop up the work and he says he can install ceramic bearings is this a recognized mod ?
Sorry for such a book of a thread Thanks again Simon
